I am encountering an issue with three textboxes all having watermarks. When I use JavaScript to set the value of the second textbox in the OnChange event of the first textbox, the text appears as a watermark. However, when I click on the textbox, it becomes empty, and upon leaving, it reverts back to the original watermark text.
Is there a way to have the text set by JavaScript display as the entered text rather than the watermark text?
This method may seem unorthodox, but it is effective. Utilizing the extender's set_Text function is crucial to ensure that your text is recognized as such, rather than mistaken for a watermark.
<!-- Avoid this: -->
onchange="document.getElementById('<%= textbox.ClientID %>').value = 'foo'"
<!-- Use this instead: -->
onchange="$find('<%= watermark.ClientID %>').set_Text('foo')"
